Hi
Genma mentioned that TrackViewer can produce an elevation chart, and in fact a full track chart as intended, I think, by ckawahara (for clarity, this is created for a path, as coded in a .pat file and that can be edited by TrackViewer). This is documented in the TrackViewer manual. Unfortunately, the manual on the Openrails.org web-site is rather out-of-date. A much more recent version can be found in the source (under Documentation directory, in .odt format). The possibility to make a track chart has also been documented in the following post
http://www.elvastowe...post__p__183745 (there are some pictures in that thread as well). There is even a not-so-well tested option to export in .json format and read this again in, say, a web-site (see the attachement in the referenced post for an example).
Regarding understanding the data structure that TrackViewer and ORTS read, I would suggest starting with MSTS tutorials on the .tdb file. See for instance
http://msts.steam4me...torials/#routes, or
http://msts-roundhouse.vnxglobal.com/, or just search for .tdb, MSTS, and perhaps tutorial.

but I'd like a separate map file to be open while driving my train.
this is supported by ORTS itself. It is called Dispatcher Window and described in section 7.5 of the OpenRails-Testing-Manual.pdf available on the openrails.org web-site.
